DEVICE FOR CONTROL AND MANAGEMENT OF SOIL ROTOTILLAGE QUALITY

摘要

FIELD: agriculture; agricultural engineering. SUBSTANCE: device has a frame, carrier wheels, and a fluid-operated drum. The hydraulic drive of the drum has a hydraulic pump, a tank, hydraulic lines, a bleeder, and a motor-operated throttle. The device is provided with a control unit, sensors of rotational speed of the carrier wheels and the drum and sensors of tillage depth and torque. The sensor of torque is mounted on the drum shaft. The control unit is a data processing unit with an 8-digit microprocessor. The initial setting circuit is connected to the microprocessor input, and the microprocessor output is connected to the main line by means of a buffer and a control signal circuit. Also connected to the main line are the ROM and RAM units, a decoder, a programmable timer, and an I/O port. The device is provided with an indicator, a dynamic speaker, and a keyboard. The indicator, the speaker, and the keyboard are connected to the main line through an indication controller, audio alarm controller and keyboard controller respectively. The outputs of the sensors of rotational speed, tillage depth, and torque are connected to the inputs of the data I/O port, and the output of the port is connected to an appropriate input of the motor-operated throttle. EFFECT: higher tillage quality; higher machine reliability.
